“Teste di mazza”: The Nuragic mace-heads (Sardinia, Italy). Technological and experimental analysis
We present the results of a study on the experimental reproduction of a specific type of macro-lithic tool, traditionally called “teste di mazza”, distinctive to the Nuragic phase in Sardinia (17th-9th century BC). We analyzed a sample collected in the area of northern Sinis–in the western-central part of the island–in order to reconstruct the sequence of the technological actions required to produce these tools. At this point, two experimental copies were manufactured, documenting the process and especially the macro-traces left on the surface of the instruments which were used to make comparisons with the archaeological data
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Le village prédynastique de Nag el-Qarmila, Aswan: problèmes de préservation et interprétation
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Le village prédynastique de Nag el-Qarmila, Aswan: problèmes de préservation et essais d'interprétation
Un des objectifs du Projet Archéologique d'Aswan-Kom
Ombo (AKAP - The Aswan·Kom Ombo Archaeological Project) est de récolter, à travers les prospections de surface et les fouilles de sauvetage, des données utiles à la reconstruction du modèle d'habitation prédynastique dans la région comprise entre Aswan et Kom Ombo. L'analyse des données du site WK15 localisées dans la vallée de Nag el-Qarmila, au Nord de Wadi Kubbaniya (environ 7 km au nord d'Aswan), par ailleurs situé à proximité de deux nécropoles contemporaines, actuellement en cours de fouilles, représente un pas important en cette direction.
Les trois campagnes de fouilles exécutées des années 2007 à 2009 ont permis de découvrir des témoignages intéressants remontant, pour ce qui concerne le village, au Nagada IC-IlB (env. 3700 BCE); dans la récolte de surface des restes attribuables à Nagada IlC-IIlA2 sont aussi présents. A la différence d'autres habitats prédynastiques situés plus au nord le long du Nil, par exemple Adaiina, Nag el-Qarrnila présente un régionalisme marqué à cause de la présence constante d'éléments Nubiens dans les données archéologiques. Il ne faut pas oublier que la région examinée constitue une zone frontière entre l'Egypte et la Nubie. Cette région se caraetérise done par l' osmose qui se crée entre la culture émergente égyptienne et le grand ferment de cultures contemporaines nubiennes, comme celle du Groupe-A. Un syncrétisme culturel qui a fonctionné comme eatalyseur du développement de la complexité sociale dans les deux régions. Cet article présente les données qui proviennent des fouilles de l'habitat, et prend en considération les graves problèmes de préservation des matériaux; une première interprétation de ces données est fournie, soutenue par des parallélismes

Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
